使用上面的代码，我得到以下窗口

在此处输入图像描述

private void btnAdd_Click(object sender, RoutedEventArgs e)
    {
        AddKeyValue(txtKey.Text, txtStringValue.Text);
    }


    private void AddKeyValue(object key, object value)
    {
        // load the resource dictionary
        var rd = new System.Windows.ResourceDictionary();
        rd.Source = new System.Uri("pack://application:,,,/LanguageResources;component/EnglishResources.xaml", System.UriKind.RelativeOrAbsolute);

        // add the new key with value
        rd.Add(key, value);

        // now you can save the changed resource dictionary
        var settings = new System.Xml.XmlWriterSettings();
        settings.Indent = true;
        var writer = System.Xml.XmlWriter.Create(@"EnglishResources.xaml", settings);
        System.Windows.Markup.XamlWriter.Save(rd, writer);
    }

如果我单击添加按钮，则应将值插入到我已经拥有的资源字典中（EnglishResources.xaml）。但它不是插入。请帮帮我。

我需要喜欢

<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:sys="clr-namespace:System;assembly=mscorlib">

<sys:String x:Key="add">ADD</sys:String>
<sys:String x:Key="key">Key</sys:String>
<sys:String x:Key="stringValue">String Value</sys:String>

<!-- the value should be inserted here. But not Insert-->

</ResourceDictionary>

添加后

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"    xmlns:s="clr-namespace:System;assembly=mscorlib">

<s:String x:Key="add">ADD</sys:String>
<s:String x:Key="key">Key</sys:String>
<s:String x:Key="stringValue">String Value</sys:String>

<!-- the value should be inserted here. But not Insert-->

</ResourceDictionary>

在我将值添加到资源字典中后，我得到了类似上面的结果。sys更改为s ，名称空间合并为一行。

你可以用这个简单的解决方案来做到这一点

private void AddKeyValue(object key, object value) {
  // load the resource dictionary
  var rd = new System.Windows.ResourceDictionary();
  rd.Source = new System.Uri("pack://application:,,,/YOURAssemblyName;component/EnglishResources.xaml", System.UriKind.RelativeOrAbsolute);

  // add the new key with value
  //rd.Add(key, value);
  if (rd.Contains(key)) {
    rd[key] = value;
  } else {
    rd.Add(key, value);
  }

  // now you can save the changed resource dictionary
  var settings = new System.Xml.XmlWriterSettings();
  settings.Indent = true;
  var writer = System.Xml.XmlWriter.Create(@"EnglishResources.xaml", settings);
  System.Windows.Markup.XamlWriter.Save(rd, writer);
}

用法

AddKeyValue("NewKey1", "StringValue");
AddKeyValue("NewKey2", 1000);

希望有帮助。
